Tucker, Pittsburgh, and Earl W. Simpson, Bethel Park, Pa., assignor-s to Koppers Company, Inc., a corporation of Delaware Filed May 28, 1969, Ser. No. 828,673 Int. Cl. Cb 29/02 U.S. Cl. 202-223 9 Claims ABSTRACT OF THE DISCLOSURE corner bricks in each horizontal course of vertically arranged courses coact with the end jamb and intermediary bricks to form the end heating fine wall.

BACKGROUND OF THE INVENTION In horizontal coke oven batteries, the end jamb brick arrangement, which includes the bricks at the extreme ends of the coking chambers and the bricks at the outer ends of the heating wall end fines, are the portions of the heating wall that are subjected to the most wear and tear and that have to be replaced most often. These end jambbricks are exposed to ambient temperature and weather conditions each time the coking chamber doors are removed for pushing coke. Sooner or later these end jamb bricks spall and crack and must be replaced.

To be satisfactory, the end jamb brick arrangement must admit of easy removal and replacement of the jamb face bricks without disturbing the other jamb bricks which are under stress from the bnckstays. Further, the jamb face bricks should be readily removable and replaceable without exposing any of the heating fines, particularly the end heating fines, to ambient conditions.

Thos skilled in the art will recognize how effectively the jamb structure of the present invention accomplishes the desired purposes.

SUMMARY OF THE INVENTION A coke oven jamb wall construction includes spaced apart end jamb bricks of equal size and shape, with a plurality of intermediary bricks disposed between. Each end jamb brick coacts with one entire end surface of one intermediary brick and with one-half of the end surfaces of the intermediary bricks in vertically adjacent courses above and below the one intermediary brick, and spaced apart corner bricks with a stretcher brick therebetween, both bricks being cooperative with the end jamb and intermediary bricks.

For a further understanding of the invention and for features and advantages thereof, reference may be made to the following description in conjunction with the drawings which illustrate for the purpose of exemplification one embodiment of the invention.

BRIEF DESCRIPTION OF THE DRAWING One embodiment of the invention is illustrated in the drawing wherein:

FIG. 1 is a schematic elevational face view of a coke oven jamb structure in accordance with the invention;

FIG. 2 is a sectional view along line 11-11 of FIG. 1; and

FIG. 3 is a sectional view along line IIIIII of FIG. 1.

DETAILED DESCRIPTION FIG. 1 illustrates an elevational view of the face of a coke oven jamb structure 11 (with bnckstays and bearing plate removed for clarification purposes) which extends from the coke oven floor 13 to the coke oven roof 15. The jamb structure 11, illustrated in FIG. 2 and FIG. 3 also, comprises the ends of a conventional heating wall 12.

The jamb structure 11 comprises alternate courses of refractory brick of differing composition. As viewed in FIG. 3, the end jamb courses of bricks 17, 19 are, preferably, but not necessarily fused silica bricks, while the courses of bricks 21a, 21b, 21c, intermediate the end jamb bricks 17, 19 are, preferably, but not necessarily silica bricks. A steel bearing plate 23 coacts with the faces of the intermediary bricks 21a, 21b, and 210, and with a buckstay 25 in a conventional manner.

It will be noted that the intermediary bricks 21a, 21b, 210 have conventional cooperative tongue 27 and groove 29 construction in both a vertical and a horizontal plane. The intermediary bricks 21a and 210 are shaped also to conform to a conventional curved steel door jamb 31.

Adjacent the intermediary 21a, 21b, 21c and the end jamb bricks 17, 19, there are a plurality of courses of bricks 33, 35, 37 which comprises the end Wall of an end heating fine 39. The bricks 33, 35, 37 are, preferably but not necessarily, silica bricks, and are similar in composition to the bricks 21a, 21b, 21c.

The bricks 33, 37 form the corners of the end heating flue 39 and have conventional ton-gue construction 41 in the vertical plane, and there is a tongue construction in the horizontal plane, as is clear from FIG. 2.

The intermediary or stretcher bricks 35 have a conventional groove construction 43 to interengage these stretcher bricks with the end jamb bricks 33, 37.

From FIG. 1 it will be noted that each one of the end jamb bricks 17, 19 vertically coacts with an end surface of an intermediary brick in course A, and one-half of an end surface of each brick in course B disposed above course A, and in course C disposed below course A, except at the top and bottom of the coke oven. At the top and bottom of the heating wall 12, the end jamb bricks coact with two and one-half end surfaces of intermediary bricks as shown in FIG. 1.

Both of the end jamb bricks 17, 19 coact with the intermediary bricks 21a, 21c by means of a conventional tongue 45 and groove 47 construction to maintain integrity and stability of the heating Wall 12.

The end jamb bricks 17, 19, it will be noted, have the same size and shape throughout, except those end jamb bricks immediately adjacent the oven roof 13 and the oven fioor 15, but the same size and shape bricks are used at the top and at the bottom of the heating wall. The intermediary bricks 21a, 21c vary in size; that is to say, in courses B and C these bricks have the same size and shape, but in course A these bricks are smaller than in courses B and C.

Likewise, the intermediary bricks 35 in all courses, have the same size and shape; the corner bricks 36, 37 of the end flue, however, are of different size in adjacent courses.

Now, then, when repairs are necessary to the jamb bricks 17 19, it is a simple matter to dig out one or more of these bricks and replace them with new bricks. Those skilled in the art will recognize that the removal of one or more jamb bricks does not expose the end heating fine to atmosphere, and that the buckstay continues to coact with the intermediary bricks as usual so that the holding power of the bnckstays is not changed in any Way.

Further, one skilled in the art will recognize the economic advantage of having all of the end jamb bricks, except those at the top and bottom, of the same size and shape. Further, one skilled in the art will recognize that it is only necessary to provide two different end jamb brick shapes; one shape being of the type used at the top and bottom of the heating wall, and the other type being those used between the top and bottom brick shapes.
